INSTALLATION INSTRUCTIONS
-------------------------

	NOTES:

	 1.  You must have OS/2 DOS Support installed in order to
	     install this driver.

	 2.  The OS/2 ATTRIB command is used during installation.  If you
	     elected not to install the OS/2 System Utility Programs or you
	     have deleted the ATTRIB, command you must use Selective Install to
	     restore the ATTRIB command before continuing.

	 3.  If you previously installed SVGA support, return to VGA resolution
	     using the new SETVGA procedure found at the end of this README
	     before you install this driver.

         4.  You must have the miro Windows Basis Diskettes.


INSTALLATION FROM DISKETTE
--------------------------

This video accelerator driver is compatible with OS/2 2.1.  Do not install it
on previous versions of OS/2.

To install this miro video accelerator driver from diskette:

    1.	Place this diskette into drive A (or any other diskette drive).

    2.	Open an OS/2 full-screen or OS/2 window session.

    3.	At the OS/2 command prompt, type the following command:

        A:MIROINST A: C:

	     where:  A: is the diskette drive
		     C: is the drive where OS/2 2.1 is installed

	This command will copy all necessary files to the OS/2 drive.

    4.	Remove the diskette from the diskette drive, perform a shutdown, and
	then restart the system.

    5.	Open the "OS/2 System" folder.

    6.	Open the "System Setup" folder.


    7.	Open the "Display Driver Install" (DSPINSTL) object.

        When the Display Driver Install window appears, "S3" should be the
	default choice.  Select "OK".

	When the Monitor Configuration/Selection Utility window appears,
	the "Install Using Defaults for Monitor Type" option is preselected.
        Accept this option. Answer the questions about your miro video card
        and the monitor.

     8. When the source directory pop-up window appears, insert the MIRO
        OS/2 display driver diskette and select Install.

	DSPINSTL determines the hardware configuration by creating the
	SVGADATA.PMI file on the drive where the OS2 directory is located.
	If the SVGADATA.PMI file has not been created, the adapter will not be
	supported.

     9.  When the installation is complete, do the following:
	 a.  Open "OS/2 System".
	 b.  Open "System Setup".
	 c.  Open the "System" object.  The Screen page of the Settings
	     notebook lists all the supported resolutions for your
	     configuration.
	 d.  Select a resolution; then, close the notebook.

    10.  Open a DOS box full screen session and start
          <Bootdrive>:\os2\wininst\install <Bootdrive>:

    11.  Follow the Win/OS2 install procedure.

    12.  Close the Win/OS2 session.

    13.  Perform a shutdown; then, restart the system.

Note that during the installation of this driver a DISPLAY.LOG file is
created in the OS2\INSTALL directory.  This file identifies the OS/2 2.1 system
files that were updated and indicates whether the installation was successful.
The contents of this file might be useful if you need to report an
installation problem to miro.



COMPATIBILITY
---------------------------------------

This video accelerator driver is compatible with OS/2 2.1.  Do not install it
on previous versions of OS/2.


FUNCTIONAL RESTRICTIONS
-----------------------


NEW SETVGA PROCEDURE
--------------------

Use the following procedure instead of the SETVGA command to return to
VGA mode.

	NOTE:  If your display is out of sync, start OS/2 using the OS/2
	       Installation Diskette, insert Diskette 1 when prompted, then
	       press Esc to access a command prompt.  Follow the instructions
	       below to reset your display mode.

o  If you installed OS/2 from diskettes:

     1.  Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory.	If it is, go
	 to step 2.  If it is not, insert Installation Diskette 8 and unpack
	 RSPDSPI.EXE with the following command:

	 C:\OS2\UNPACK A:\INSTAID C: /N:RSPDSPI.EXE

	     where:  A: is the drive containing Installation Diskette 8
		     C: is the drive where OS/2 2.1 is installed

     2.  Type C:; then press Enter
     3.  Type CD C:\OS2\INSTALL; then press Enter
     4.  Type RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:; then press Enter

	     /T:C: where C: is the drive where OS/2 2.1 is installed
	     /S:A: where A: is the diskette drive you use to install
		   OS/2

o  If you installed OS/2 from CD-ROM or a LAN:

     1.  Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory.	If it is, go
	 to step 2.  If it is not, unpack RSPDSPI.EXE with the following
	 command:

	 C:\OS2\UNPACK E:\DISK_8\INSTAID C: /N:RSPDSPI.EXE

	     where:  C: is the drive where OS/2 2.1 is installed
		     E: is the CD-ROM or LAN drive

     2.  Type C:; then press Enter
     3.  Type CD C:\OS2\INSTALL; then press Enter
     4.  Type RSPDSPI /PK:VGA /SK:NONE /S:E:\OS2SE21\ /T:C:; then press Enter

	     /T:C: where C: is the drive where OS/2 2.1 is installed
	     /S:E: where E: is the CD-ROM or LAN drive
